AIR CONDITIONING/PRESSURIZATION
Sep 13/2004 Flight Crew Operating Manual Volume 2
REV 1 CSP 100-6 02-04-05
CONTROLS AND INDICATIONS
PRESSURIZATION CONTROL PANEL
MANUAL RATE KNOB
The MAN RATE knob allows the crew to control how fast the cabin pressurization system reaches the desired
cabin altitude. The switch allows adjustments to the manual pressurization rate toward DN or UP positions, as described
below:
- The 12 o’clock position corresponds to 0 SLFPM
- The cabin rate of change demand from -1000 to +1000 SLFPM (sea level feet per minute) is obtained over
approximately two thirds of the potentiometer angle range to allow easy selection by the aircrew
- The cabin rate of change is limited to 2500 SLFPM, which is obtained by setting the potentiometer in the full
counter-clockwise position, full clockwise position, which corresponds to the max DN and UP positions, respectively.
When the desired cabin altitude is approached, rotate the switch to center position, to stabilize the cabin at the
selected altitude.
MANUAL PRESSURIZATION SWITCH
Manual control of the pressurization system is initiated by pressing the MANUAL switch ON.
LNDG ALT KNOB
The LDG ALT knob is used to select landing field elevation during automatic pressurization mode. The LNDG ALT control
consists of two concentric knobs. The outer knob can be selected between MAN and either FMS (for a single installation)
or FMS 1 and FMS 2 (for a dual installation). Selection of one of the FMS settings will allow the pressurization landing
altitude to be set from the applicable FMS destination airport database. Selection of MAN allows the inner knob to control
the pressurization landing altitude
EMER DEPRESS SWITCH
The EMER DEPRESS switch is an alternate-action switch located on the PRESSURIZATION panel. A guard is installed
over the switch to prevent inadvertent actuation. The switch is used to depressurize the cabin for smoke and fume evacuation.
The EMER DEPRESS function is available in both automatic and manual modes. In AUTO mode, when EMER DEPRESS
is selected ON, the cabin will depressurize at 2500 SLFPM up to 14 000 ft ± 100 ft or the aircraft altitude, whichever
is lower. In MANUAL mode, when EMER DEPRESS is selected ON, the cabin will depressurize at 3000 SLFPM up to 14
500 ft ± 500 ft or the aircraft altitude, whichever is lower.
NOTE: In manual mode, the cabin may also be depressurized by selecting MAN RATE to max UP from the
control panel.
DITCHING SWITCH
The DITCHING switch is used to depressurize the cabin, shut off the air conditioning, and then keep the OFV closed in
the event of a water landing. The sequence activates automatically, and is inhibited above 15 000 ft.
NOTE: The ditching function is not available in manual mode. To close the outflow valve, turn the MAN RATE knob
to max down.
